A bit off-topic here but...
The problem with that philosophy is that it forces you to remain a subscriber, even if you're not happy with the way things are. Normally, if you don't like the direction the project is going, or the way the developer does things, you unsubscribe as a way of showing your displeasure. However, the moment you do so your opinion stops being relevant because you're no longer a supporter and therefore "not allowed to complain".
You see the problem here? It's a catch 22.
Not just that, people are always shoving aside those who have any form of criticism, be it moderate* or otherwise. "You're not happy with the development? Then unsub... Oh, you just unsubed? Then your opinion no longer matters. GTFO." This means only those who are happy with the system are allowed to remain and have a say in the direction of the project.
"Yes-men" are insidious "friends". They are good for your self-esteem and moral but it will cost you long-term, when problems crop up and keep growing just because no one has the courage to set you straight, lest they hurt your feelings...
*1- While not all criticism is created equal, some people can be extremely defensive towards it all, even the constructive kind. When that happens, bitterness and toxicity usually follows suit.
